Nah, likely just the Beyer T1 and the Audeze LCD-2. :mrgreen:
I listen to the Senn HD800 either straight from a 5th gen iPod (off the AC grid!), or from an iMac with a USB connected Griffin Powerwave class T (Tripath technology) amp and have fun. I know it's far from what the HD800 can do, but it still sounds quite good. I had a Headroom Supreme, but killed it plugging in a home made battery pack backwards... so stupid. :x
I could hook up my Sony SACD player to a tube pre amp I built to this Griffin, but meh. And I could hook up my VPI record player to a Rega phono stage to the tube pre amp, but meh. Or buy a Toslink cable and put it between the iMac and a Theta Cobalt DAC, to the tube pre amp, to the Griffin amp, but meh...
I'm just getting reaquainted with serious listener mode. I'm all in the zone, having fun, the night slips away, it gets later than I realize and then it's too freakin late and I have to go to bed. It's amazing how time flies when you're having fun. :mrgreen:
